Magnetotellurics unveils a hidden caldera complex beneath the Cappadocia Volcanic Province, Central Anatolia, Türkiye

Hasan Dağı Volkanı ve Çiftlik-Bozköy (Orta Anadolu) Gömülü Kalderasını Besleyen Aktif Magma Odalarına İlişkin Isı Transferi Analizleri

“…In contrast, under the Çiftlik-Bozköy region, very low resistivity values were detected at depths of 2-4 km, precisely beneath the centre of the depression area, suggesting a caldera structure. However, it is important to highlight that data regarding the magma chamber in this region were not presented in the findings by Hacıoğlu et al (2023). However, it is evident that the outcomes derived from numerical modeling studies, assuming the presence of a magma chamber beneath this region (Dornadula et al, in press), do not align with recent magnetotelluric results (Hacıoğlu et al, 2023).…”

“…Bu açıdan, güncel manyetotellürik çalışmalarının bir magma odasının bulunmadığını belirtmeleri sebebiyle, Şahinkalesi (Çiftlik-Bozköy) volkanik bölgesi altında 5 km derinlikte bir magma odasının varsayımıyla gerçekleştirilen nümerik modelleme sonuçlarının (Dornadula vd., basımda) yeniden değerlendirmeye ihtiyaç vardır. (Tank and Karaş, 2020) and b) Çiftlik-Bozköy (Hacıoğlu et al, 2023).…”

“…Their findings suggest the presence of a potential magma chamber with a depth of 4-6 km and a width of roughly the same magnitude, in two-dimensional profiles extending approximately 45 km southwest of Hasandağı towards the Niğde plain. Hacıoğlu et al (2023) have identified a buried caldera with a depth of 3 km and a diameter of up to 12 kilometers, following MT studies conducted in 60 locations, including the Çiftlik region north of Melendiz Mountain. However, researchers reported that have yet to find definitive evidence of a magma chamber in this area (Hacıoğlu et al, 2023).…”
